SEG Solar has announced plans to establish a 4 GW solar module manufacturing facility in Houston, US. The facility represents an investment of more than $200 million, expanding SEG’s total annual US solar module production capacity to approximately 6 GW. The facility is expected to commence operations in the third quarter of 2026. Furthermore, the expansion follows SEG’s plans for a 5 GW ingot and wafer manufacturing facility in Indonesia, strengthening its fully integrated solar supply chain across ingots, wafers, and cells.
In December 2025, SEG Solar announced plans to develop a 3 GW ingot and wafer manufacturing facility in Batang Regency, Indonesia. The project forms phase I of a broader 5 GW expansion plan for ingot and wafer production. The proposed manufacturing facility is expected to involve an investment of about $80 million, fully funded by SEG. Moreover, production at the plant is scheduled to begin in the third quarter of 2026.
In November 2025, First Solar announced plans to set up a new facility in Gaffney, South Carolina, to complete the production process for its Series 6 Plus modules. The company plans to invest approximately $330 million in the plant, which is scheduled to begin commercial operations in the second half of 2026. The facility is expected to add 3.7 GW of manufacturing capacity.
REGlobal’s Views: The tightening of solar imports, changing geopolitics and ensuring supply chain risks for solar projects have led to an uptick in expansion of solar manufacturing facilities across the US. Many players like SEG Solar have announced new factories to expand their portfolios, especially as the US continues to be a top solar market witnessing massive investments despite policy flux.
